It's unique for the Japanese market, but nothing we haven't seen already in the West. That goes for both the messages regarding discrimination and racism, the art style, the story beats and tropes within the story... The plot's central mystery is done well enough, short and sweet, but you know the culprit right away. Once the story actually reveals it, you're left wondering if there will be more to it, whether there will be some problems faced in trying to catch them, but then the series resolves quick and neatly. It's only 3 volumes long after all. It doesn't feel rushed per se, just kinda like"Oh, that's it." Never really had an "Oh, shit!" moment.

It's competently done, nothing new for me personally, but if it is new for you, then it's good.
